UNLOADING OR LOADING DEVICE.

SPECIFICATION forming part of Letters Patent No. 661,154, dated November6, 1900.

Y .indication ined August 2s, 1895. stanno. 560,244. cammen Thisinvention relates to unloading and' loading devices. Y

The object is in a ready and efficient manner to effect the unloading ofsugar-cane or the like from a cart or Wagon and to transport it to anydesired point, whence it may be conveyed tc a mill or to a place ofstorage, the whole being effected without hoisting or separate liftingof the load; furthermore, to provide a novel arrangement of platform tobe used in conjunction with au overhead trolley or other form of movablesupport, the platform being so constructed that forward movement thereonwill serve to bring the vehicle containing the cane to a position Wherethe cane may be connected through its binderI with the trolley and thefurther movement of the vehicle in the same direction will operate tounload the cane from the vehicle and leave it suspended from thetrolley.

In an unloading and loading device characterized by our invention weprovide an overhead track upon which is adapted to run a trolley havingsupporting means attached thereto, such as chains, hooks, or the like.

At one end of the overhead track or that end that will be the loadingend in operation and beneath a point where the trolley may be mosteffectively reached we provide a platform constructed with a centralhorizontal portion and two oppositely-inclined end portions. At theopposite end of the track or that end Which'will in. operation be theunloading end we provide an inclined section of track which is arrangedover an endless carrier for conveying the cane or other material to aplace of use or of storage. As a matter of further improvement and asamodification of the form of device just described We may in someinstances dispense with the inclined platform at the loading end of thetion as the platform.

track and employ in lieu thereof an inclined track-section forsubserving the same flinc- Instead of having a single track we may haveaseries of tracks diverging from a main track and extending to abuilding or other place of storage, by which means cane in bundles maybe stored away until ready to be used.

Further and more specific details of construction will hereinafter befully described.v

In the accompanying drawings, forming a part of this specification, andin which like letters of reference indicate corresponding parts, we haveillustrated two of many forms of embodiment of our invention. i In thedrawings, Figure lis a View in side elevation showing the overhead trackwith its loading end horizontal and with a double inclined platformarranged beneath this end, and showing also the unloading end of thetrack as inclined toward an endless carrier arranged beneath orcontiguous to this latter end. Fig. 2 is a view in end elevationdisplaying inore particularly the manner in which the tracks are bracedagainst sagging and also the peculiar construction of the trolley. Fig.3 is a view in side elevation of -a modified form of track, showing thein- Supported by and adapted to run upon the.

track is a four-wheeled trolley B, the axles of which are connected toprevenl spreading by side bars b, and from the axles of the trolley aresuspended hangers b3, each having its lower end provided with an eyeb4,vadapted to be engaged by the end link or links of a chain O, whichlatter constitutes a'binder for holding the cane or the like assembleduntil discharged upon a carrier or other conveying means. It is to beunderstood that the connection of the chain with the eye b4 is to be lOOof such nature that it may be readily detached therefrom, so that wherethe cane is to be stored away the bundles will remain intact when thechain is disengaged from the eye; also, that instead of employing achain the binder may be of rope, wire, or the like.

The track A is provided at its rear or nnloading end with an inclinedsection (t5, arranged over an endless carrier D, which carrier operatesto convey the cane to the desired point, as to a mill ora place ofstorage. In some instances an inclined dumping-platform may be employedinstead of the conveyer.

Arranged beneath the front or loading end of the track is a platform E,constituting what may be termed an unloading-platform. This platformcomprises a central horizontal section e and two oppositely-inclined endsections e2 e3, respectively, the height of the center section e beingsuch that when the cart or wagon is resting thereon the binders mayreadily be attached to the eye of the hangers.

The operation of the device is as follows: A cart filled with cane, asindicated in Fig. 2, is driven up the incline e2 and stopped on thecenter platform e. previously been secured around the cane are thenconnected with the eyes of the hangers, or, if preferred, with a shortsection of chain depending from each of the hangers, and as the cartmoves oli from the section e and down the end portion c3 its body Willclear the load and leave it suspended from the trolley. The trolleycarrying the load is then pushed along the track until it reaches theinclined portion a5, whereupon it will run down and deposit the loadupon the carrier D. As the trolley runs down the said inclined portionthe strain is taken off the binders, permitting them to be disengagedfrom the hangers or be removed from around the cane. The carrier maythen transport the bundle or the loose cane, as the case may be, to aplace of use or of storage.

Insteadof locating the inclined tracksec tion at the rear or unloadingend of the track we may, if preferred, arrange this section at the frontor loading end of the track F, as shown in Fig. 3. In this arrangementthere is at the loading end of the track a short horizontal section f,upon which the trolley rests when a load is to be carried away, and eX-tending rearward from this section is an upward-inclined section f2,which connects with the main track f3, leading to a mill or place ofstorage. Zhen this arrangement of track is employed, the platform E isdispensed with, as the section f2 subservesits function. The operationof this latter form of device is as follows: A cart containing bundledcane The binders which have drives under the loading end of the track,and the binders are connected with the hangers, as has already beendescribed. The cart is now driven toward the unloading end of the track,thereby drawing the trolley up the inclined section f2 and lifting theload free of the body of the cart. The load is then Apushed to the rearend of the track and disposed of.

It will be observed that in both forms of device the load does not haveto be hoisted or separately lifted, the platform E in Fig. l and theinclined track-section f2 in Fig. 3 operating mechanically to remove theload from the cart.

It is to be understood that, if desired, the track F may also beprovided with an inclined section at its unloading end While we haveshown but one trolley in this instance, it is obvious that a greaternumber may be employed; also, that their construction may be varied.

In some instances an inclined platform may be formed, from which theload may be taken direct by tilting the body of the cart.

Having thus fully described ourinvention, what we claim as new, anddesire to secure by Letters Patent, is-

l. An unloading and loading device comprising au overhead track, atrolley normally stationary thereon but free at all times to bepropelled by an agent independent of and disconnected frorn it, andmeans acting to lift or clear the load from the vehicle that contains itby the movement of the vehicle itself, alone, and leave the loadsuspended from the trolley, substantially as described.

2. An unloading and loading device comprising an overhead track, atrolley normally stationary thereon but free at all times to bepropelled by an agent independent of and disconnected from it, and meansacting antomatically to lift or clear the load from the vehicle thatcontains it by the movement of the vehicle itself, alone, and leave theload suspended from the trolley, substantially as described.

An unloading and loading device, comprising an overhead track, having aninclined end portion, trolleys adapted to run thereon, a conveyerarranged below the inclined portion, and a double inclined platformlocated below the track at the end opposite the inclined portion,substantially as described.

In testimony whereof we affix our signatures in presence of twowitnesses.
